WINDOW-SCREEN.

EPEOIFICATIGN forming part of Letters Patent No. 290,568, dated December 18, 188?.

Application filed July 24, 1883. (Model) To all whom it may concern:

Be it known that I, HERMAN F. GEIST, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in a'Oombined Sash-Balance and Window-Screen; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it pertains to make and use the same.

My invention relates to improvements in a combined sash-balance and window-screen; and it consists in certain features of construc tion and in combination of parts hereinafter described, and pointed out in the claims.

The object of my invention is to provide spring-rollers to sustain the weight of window-sash, instead of the cord and weight in common use, and to attach thereto screens, preferably of wire-gauze, in such a manner that when the window is opened the opening may be covered with the said screen.

In the drawings, Figure l is a vertical crosssection of a window provided with my new balance and screen. Figs. 2 and 3 are longitudinal sectional views of the rollers shown in Fig. 1. Fig. 4 is a detail drawing.

A represents the top sash or upper part of the window, and is supported from the springrollers B by means of the screen a. When the sash is. closed, as shown, the screen is out of sight, nothing pertaining to it appearing except the stripb, to which the screen is attached, and the catch b, that attaches the strip to the sash. The stops d, that separate the sash have narrow grooves on their faces that embrace the edges of the screen, so that there is no opening at the sides through which insects can pass.

A is the lower sash with the strip 11 and the catch 2) attached, the same as is shown on the sash above.

B is a spring-roller similar to 13, except in the tension of the spring, that only requires sufficient force to roll up the screen a. The

weight of the sash A is sustained by the roller 0 above, and connected with the sash, preferably by small wire cables. -When the sash A is raised, it draws the screen after it, so that the opening exposed by raising the sash is covered by the screen a.

The construction of the roller C is shown in Fig. 2, and the construction of the rollers 13 and B are shown in Fig. 3. A suitable construction of the catches b is shown in Fig. 4.; but other kinds might be used. The roller 0 has a spool-like depression at each end, on which to wind the wire cables D. Inside of the roller is the rod or spindle 0, around which is coiled the spring 0, one end of which is attached to the rod 0 on the right hand, while the other end of the spring is secured to the block F. This block is made fast to the roller, so as to turn with it, either by a snug fit in the roller or in any other manner. The block, as shown, has a hole in which the rod 0 fits loosely, and a coil-spring, j, that presses the rod 0 endwise and causes a clutch attached to the other end of the rod 0 to engage the cap H on the end of the roller 0. The outer end of the rod 0 is squared, and when in place engages a square socket in the flange G, that is made fast to thewindow-casing.

At the left-hand end of the roller G is the cap H, with a central hole therein, to engage the plug is, upon which the roller turns. This plug is attached to the support K, as shown, and has a groove where it is embraced by the spring k, that forces the plug k forward, as shown. The plug may be forced back to the left until it is flush with the right-hand side of the part K, to admit the roller. vVhen the roller 0 is in place, the spring 71: holds the plug it forward to its pivotal engagement with the roller; also, when the roller is in position, it about fills the space between the parts G and K, so that the end of the rod 0, coming in contact with the bottom of the socket in G, is pressed inward, compressing the spring f and relieving the clutch h. This part of the device operates as follows: 'When the roller is out of its bearings, the spring f keeps the clutch h to its engagement with cap H and prevents the roller from turning in one direction, and that is in the direction that releases the ten sion of the spring. A wrench may be applied to the end of the rod 0 and the rod turned so as to cause any desired tension of the spring, the clutch h holding the rod from being turned back by the spring. \Vhen, however, the roller is placed in its bearings, as aforesaid,

the rod is pressed inward, breaking the engagement of the clutch h, and leaving the roller actuated in one direction by the recoil of the spring and in the other direction by the weight of the sash. If the spring has been wound up to its proper tension, these two forces will balance each other, and the sash will remain at. any .position in which it is placed. The roller shown in Fig. 3 is made of equal size the whole length of the roller part, and is therefore suitable for attaching the screens, and may be usedat B or B. The clutch is intended to be the same as shown in Fig. 2, but is here shownin section. To the right in this figure is shown a bracket-bearing, 9, with a square socket, similar to that shown at G, Fig. 2. WVhen it is desired to use bracket-bearings, a cap like J may be used, having a pivot, j, for a bearing, attached. In such case a bracket forthe end may be like ordinary brackets for window-shades, with a slot that admits of the pivot being placed in position. These bracket-bearings willbe used only when the rollers and screens are applied to old window-frames,.and will have to be modified according to circumstances. These brackets must be placed so near together that the bracket y will force the engaging-rod 0 far enough endwise to disengage the said clutch h. In all cases where the brackets are not used the cap H and its attendant device K will be used in place of the cap J and its slotted bracket above referred to.

When desired, by means of the catches Z),

' the strips bmay be disconnected from the sash and the sash operated or taken out of the window-casing without disturbing the screens or rollers.

What I claim is 1. Inawindow-screen, the combination,with 0 the upper and lower sashes, of a spring-actuated roller situated in the frame above the upper sash and provided with a screen, a springaetuated roller situated in the frame above the lower sash and provided with sash-hold- 5 ing wires or cords, anda spring-actuated roller situated in the frame below the lower sash and provided with a screen, all of the above parts adapted to operate as described.

2. The combination, with a spring-roller above, provided with'a suitable connecting device, and adapted to balance the lower sash, of a spring-roller below,provided withascreen, also attached to the sash, and adapted to cover with the screen any opening made by raising the sash, substantially as described.

3. In combination with a spring-roller provided with a screen, the strips 1) and the catches 2), adapted to form a detachable attachment between the screen and sash, substantially as shown and described.

4:. In a combined sash-balance and windowscreen, grooved stops between the sash,.adapted to embrace and guide the edges of the screen, substantially as and for the purpose set forth.

5. In the bearing K, the combination of the plug 70 and the spring 7c, substantially as described, and for the purpose specified.

In testimony whereof I sign this specification, in the presence of two witnesses, this 17th 70 day of July, 1883.

HERMAN F. GEIST.
